Presearch is an open, decentralized search engine that rewards community members with Presearch Tokens for their usage, contribution to, and promotion of the platform. In a world where one company controls 77% of all searches, influencing trillions of dollars in spending, shaping perceptions and effectively acting as the primary gatekeeper to the Internet, a new, open and community-driven search engine is a necessity. Presearch has an innovative go-to-market strategy to target the most frequent searchers - web workers - and gain early adoption, on our way to releasing future versions of the open source platform that will utilize a blockchain-based index, curated by the community.
Myriadcoin is the first coin to implement five different Proof-of-Work hashing alrogithm in the same coin, namely Scypt, SHA256D, Qubit, Skein and Groestl. This multiple hashing algorithm serves to make mining fairer and encourage even distribution. Each algorithm has the same chance of solving the next block and has its own independent difficulty while using the same difficulty adjustment method. Each algorithm aims for a block generation time of 2.5 minutes. Any existing CPU,GPU and ASIC miners can be used to mine Myriadcoin. Over the five algorithms, a block should be found on average every 30 seconds. Every 967680 blocks, the block reward halves in order to reduce inflation. Difficulty is adjusted after every block. Myriadcoin was launched on 23 February 2014.
